Overview:
ACCEL HP Spark Plugs are made with a Copper core which is a better conductor than Platinum and Iridium. They deliver a stronger spark especially in high performance applications where high combustion pressures are present. Copper is much better at dissipating heat than other materials which lessens the chance of a misfire. ACCEL HP Spark Plugs are gapable allowing you to open the gap exposing a larger flame kernel or close it if needed for high boost applications. All ACCEL HP Spark Plugs have machine rolled threads allowing for a more precise thread engagement and torque retention.
Features:
- The Copper core is a better conductor than Iridium or Platinum plugs
- Copper dissipates heat much better than other materials
- "C" - Cut Design un-shrouds the spark kernel for a better burn
- Unlike Iridium or Platinum plugs, the ACCEL HP plugs are gapable
- Machine rolled threads for precise thread engagement
- One step colder than stock
- Whether using on the street or on the strip, ACCEL HP Copper Core spark plugs deliver!

Absolutely Worth It!
Size: Standard
I've been using the Schenley Steam Mop for a few weeks now, and I'm genuinely impressed with how well it cleans. The steam heats up very quickly, and I love that I can clean my floors without using harsh chemicals. It easily removed dirt and sticky spots from my tile floors and left them looking fresh and sanitized. Very happy with the purchase!

CORD is TOOOOOO SHORT!
Size: Compact
Update: Schenley Customer Service paid attention to my review. While they obviously couldn't fix the short cord, they did send extra pads.
I appreciate this effort. I will need to use an extension cord, when using. Not sure how Schenley could rectify- maybe with a credit towards the purchase of their upgraded model, with longer cord?
This Steam Mop does a great job. It leaves no water residue after you've mopped. This is a change from a previous steamer I owned. If this mop's cord was longer, flexible, and containable with the unit, I would have given this five starts. Unfortunately, the cord is extremely short, making it impossible to do a downstairs using one plug socket. You have to turn the unit off, unplug, and then plug in to another socket. This happens multiple times during the process. The unit heats up quickly, but we shouldn't have to constantly plug/unplug turn off/turn on the unit in order to accomplish the job. Schenley needs to make a better, longer cord for this unit. Then, I'll give it five stars.

Love them!
Color: BlackNatural
This knife set exceeded my expectations! The knives are extremely sharp right out of the box and cut through meats, vegetables, and bread with ease. The German high carbon stainless steel feels durable and high quality, and the handles are comfortable to grip while cooking.
I also really like the sleek black knife block — it looks modern and stylish on the counter without taking up too much space. Having 14 pieces included makes this a great complete set for everyday cooking. So far the knives have held their edge well and clean up easily. Excellent value for the price and a great addition to any kitchen!

Love the design of the container that the knife stand up in. The knives are super sturdy and sharp.
Color: Peach Pink
They are very nice and they’re very sharp. I surprisingly found them in pink to match my kitchen, which is great. They’re very easy to use and it looks like they will last quite a while.
